摘　　要：煤层气洞穴完井在国外应用广泛,其造洞穴技术主要包括人工动力造穴、机械造穴、水力造穴以及化学造穴等类型。实验分析表明:人工动力造穴方式的增产作用最为明显,但其成本和技术要求较高;机械造穴方式最简单,综合效果最佳,地质适应性强,成本较低;化学造穴增产效果超过水力造穴;水力造穴方式相对其他几种方式而言增产效果较差,其技术难点有待突破。Cavity completion of CBM as an emerging technology has gradually been widely used abroad by means of building cave in completion of CBM,including artificial momentum way,mechanical way,hydraulic way and chemical way. In this paper,these building-cave techniques are under series of studies. In conclusion,the stimulation effect of artificial momentum way is most obvious; mechanical way is the easiest way,and the combined effect is the best; the stimulation effect of chemical way is better than hydraulic way.
